There should be a valve you have to open or close to get the pump to draw in the rv antifreeze. On my rv, the configuration of the valves says, "winterize". Im not sure of your rv, but it should have a valve somewhere. It might be near the pump on one of the input lines. You would think it would be in sight of the antifreeze intake line.
